最近的研究表明，儿童的认知表现与各种健康结果有关，但这种关系的性质尚不清楚。目前尚不清楚这种关联是否发生在认知表现的连续体中，以及它是否独立于社会经济地位。特曼生命周期研究的前瞻性数据被用来评估儿童智商（IQ）与成人死亡率之间单调关系的假设，并确定是否存在一个阈值，超过这个阈值，智商的保护作用就不再明显。1922年，总共招募了897名学龄儿童，他们在斯坦福-比奈智商测试中得分为135或更高。Cox比例风险回归用于估计64年期间的生存率。儿童智商15分的优势与死亡风险的降低显著相关（风险比= 0.68,95%可信区间：0.49,0.93）；除此之外，死亡风险趋于稳定。当样本局限于那些父亲从事非体力职业的参与者时，结果相似。童年时期的智商，即使在分布的顶端，也是死亡率的重要预测指标，与童年时期的社会地位无关。
Recent research suggests that childhood cognitive performance is associated with various health outcomes, but the nature of the relation is not well understood. It is unclear whether the association occurs across the continuum of cognitive performance, and if it is independent of socioeconomic status. Prospective data from the Terman Life Cycle Study were used to evaluate the hypothesis of a monotonic relation between childhood intelligence quotient (IQ) and adult mortality and to determine whether there exists a threshold beyond which the protective effects of IQ are no longer evident. A total of 897 individuals of school age who scored 135 or higher on the Stanford-Binet IQ test were recruited in 1922. Cox proportional hazards regression was used to estimate survival over a 64-year period. A 15-point advantage in childhood IQ was significantly associated with a decreased risk of mortality (hazard ratio = 0.68, 95% confidence interval: 0.49, 0.93) for IQ scores up to 163; beyond that, the risk of death plateaued. Results were similar when the sample was limited to those participants whose fathers had nonmanual occupations. Childhood IQ, even at the upper end of the distribution, is a significant predictor of mortality, independent of childhood social position.
